Description

  The present invention relates to a packing structure for eaves.

Conventionally, when a plurality of rectangular eaves opened upwards are stacked vertically and stored in a box such as cardboard, the upper space above the uppermost eaves inside the box is the upper cushion made of polystyrene foam. There is a known eaves packaging structure in which the space below the lowermost eaves inside the box is filled with lower cushioning material formed by reclaiming used paper and making paper presses. (For example, refer to Patent Document 1).
Japanese Utility Model Publication No. 5-62487

  The packaging structure of eaves as described in Patent Document 1 is, for example, when there is an impact from the outside during the handling of the box that houses the eaves, and there is no gap in the space inside the box. By receiving an impact with the buried cushioning member, the box body itself is deformed or damaged, or the stored eaves are deformed, damaged, or the stacked eaves are in contact with each other so that the surface of the eaves is not scratched. Yes.

  However, when a strong impact is applied to the eaves packaging structure as described above, the shock is not sufficiently mitigated by the cushioning member, and the eaves are deformed, damaged, or scratched. In some cases, it has not been possible to prevent such problems sufficiently. For this reason, the actual situation is that an eaves packaging structure that can reduce the impact on the stored eaves as much as possible is desired.

  The present invention has been made in view of the circumstances as described above, and can prevent deformation, breakage, scratches, and the like of the eaves against an impact on the box body in which the eaves are stored. It is an object to provide a packaging structure.

In order to solve the above-mentioned problems, the present invention firstly has a packing structure for eaves in which eaves having an ear at the upper end of a side wall standing from both side edges of the bottom wall are stacked and stored in the box. In the uppermost eave ridge , an upper cushioning member, which is a rectangular cylinder that fits in the eave ridge, is arranged, and below the lowermost eave ridge are respectively in contact with the bottom wall and both side walls of the eave ridge. A lower cushioning member consisting of a bottom plate and a side plate in contact with each other is disposed. Further, at least the bottom plate of the lower cushioning member is made of a cushioning material having a shock absorbing space, and the upper end of the side plate is not in contact with the ear portion.

  Second, in addition to the above features, the cushioning material having the shock absorbing space is a cardboard material.

Third, in addition to the above features, the upper cushioning member is a cardboard material .

  According to the first aspect of the invention, since the bottom plate of the lower cushioning member is a cushioning material containing the shock absorbing space, the bottom plate absorbs an impact from below the box, and the bottom wall and bottom of the lowest eaves It is possible to avoid deformation, breakage and abrasion of the corner eaves.

  In addition, the bottom plate and both side plates of the lower cushioning member are in contact with the bottom wall and both side walls of the lowest eaves so that the eaves and the box can be shifted or wobbled due to vertical or horizontal shaking. Even if it occurs, the eaves and the lower cushioning member can move together, reducing the friction and impact on the bottom wall and bottom corner of the lowest eaves and avoiding scratches and damage be able to.

Furthermore, the upper surface of the upper cushioning member abuts on the box top plate to form an impact absorbing space between the upper end of the uppermost eaves and the box top plate, thereby absorbing shock from above the box. At the same time, since the impact is not directly applied to the ear part of the uppermost eaves, it is possible to avoid deformation, breakage, and abrasion of the ear part. In addition, since the upper cushioning member is a rectangular tube that fits inside the eaves, it is possible to disperse the impact on the contact surface with the eaves, further increasing the impact resistance and reducing the weight. Costs can be reduced.

  According to the second aspect of the invention, in addition to the effects of the invention described above, the cushioning material having the shock absorbing space is a corrugated cardboard material, whereby the weight can be reduced and the cost can be reduced.

According to the third aspect of the invention, in addition to the effects of the above aspect of the invention, the upper cushioning member is made of a corrugated cardboard material, thereby further reducing the weight and reducing the cost.

  FIG. 1 is a cross-sectional view showing an embodiment of the packaging structure for eaves of the present invention.

  When packing a plurality of eaves 6, for example, the packing structure 1 of FIG. 1 can be used for packing using the lower buffer member 2 and the upper buffer member 3. Hereinafter, embodiments of the present invention will be described in detail.

  In the lower buffer member 2, side plates 22 are erected on both side edges of the bottom plate 21, and the bottom plate 21 and the side plates 22 are in contact with the outside of the bottom wall 41 and the side wall 42 of the lowest eaves 4. In addition, the upper end of the side plate 22 of the lower cushioning member 2 is located below the ear 43 of the lowest eaves rod 4 and is not in contact with the ear 43.

  The bottom plate 21 of the lower cushioning member 2 is made of a cushioning material containing the shock absorbing space A. For example, as shown in FIG. 1, the cushioning material may be a corrugated cardboard material, or may be a cushion material such as a general sponge or cotton. Further, the material other than the bottom plate 21 of the lower cushioning member 2 is not particularly limited. However, in consideration of cost and lightness, a cardboard material can be preferably used, and the same as the bottom plate 21 of the lower cushioning member 2. Costs can be reduced by integrating the materials.

  Normally, when the box 7 is placed on the floor during transportation, it receives an impact from below the box 7, and the impact is first applied to the bottom wall 41 of the lowest eaves 4 to be deformed or damaged. , Leading to scratches. In such a case, in the present invention, since the bottom plate 21 of the lower cushioning member 2 is made of a cushioning material containing the shock absorbing space A, the impact is not directly applied to the bottom wall 41 of the lowest eaves 4 but the bottom. Scratches and breakage of the wall 41 and the bottom corner 44 can be avoided.

  Further, in a car being transported, vertical or horizontal shaking also occurs, and the eaves cage 6 (especially the lowest eaves cage 4) and the box body 7 are displaced or rattled. Many corners 44 are scratched or damaged. In such a case, in the present invention, since the bottom plate 21 and both side plates 22 are in contact with the bottom wall 41 and both side walls 42, the lower cushioning member 2 can move integrally with the lowest eaves 4. It is possible to reduce the friction and impact applied to the bottom wall 41 and the bottom corner 44 of the lowest eaves ridge 4, thereby avoiding scratches and breakage.

  On the other hand, the upper cushioning member 3 is disposed in the uppermost eaves 5, and the upper surface 31 is in contact with the top plate 71 of the box 7. With this configuration, an impact absorbing space A is formed between the upper end of the uppermost eaves 5 and the top plate 71.

  In other words, the upper surface 31 of the upper cushioning member 3 is positioned above the ear 53 of the uppermost eaves 5 as a relative position and can form the shock absorbing space A. There is no particular limitation. It is desirable to select appropriately considering the weight, cost, etc. For example, as shown in FIG. 1, the upper surface 31, the lower surface 32, and both sides are in contact with the bottom wall 51 and the side wall 52 of the uppermost eaves 5. A corrugated cardboard material that is formed of four surfaces 33 and is a rectangular cylinder is selected.

  Usually, when storing the box body 7, the box body 7 is loaded and stored on top, so that the box body depends on the moment when a separate box body is placed on the box body 7 and the weight of the loaded state. 7, a load is applied to the eaves bowl 6 laminated inside, particularly the ear 61 that is densely laminated, causing deformation and breakage. In such a case, in the present invention, the shock absorption or weight from above is not directly applied to the ear portion 53 by the shock absorbing space A between the upper end of the uppermost eaves 5 and the top plate 71. The deformation and breakage of 61 can be avoided.

For example, as a packing procedure,
(A) First, the lower cushioning member 2 is placed on the bottom of the box 7,
(B) Next, the eaves bowl 6 is fitted on the lower cushioning member 2,
(C) And, the upper cushioning member 3 is inserted on the uppermost eaves bowl 5,
(D) Finally, the top plate 71 of the box 7 is closed,
Can be packed. Here, a plurality of eaves rods 6 are inserted, but they may be inserted one by one, or a combination of eaves rods 6 may be inserted. Alternatively, the box body 7 may be assembled after the lower cushioning member 2 is placed on the surface corresponding to the bottom of the box body 7 as a developed body before being assembled into the box, and the eaves cage 6 and the upper cushioning member 3 are inserted. However, when assembling the box later, the insertion work is simple, but since the stability when the eaves 6 are stacked is lacking, it can be suitably used when the number of eaves 6 is small.

  Of course, the present invention is not limited to the above examples, and it goes without saying that various aspects are possible in detail.

It is sectional drawing which showed embodiment of the packing structure of the eaves of this invention.
